Hello, I'm trying to install the latest dev branch of yt on my Ubuntu 11.10 laptop using the install script (with all default values) and run into trouble once it gets to the installation of yt. Here is the tail of the install log: /bin/sh: svnversion: not found PNG_LOCATION: png.cfg: /home/mike/Downloads/yt-x86_64/include, /home/mike/Downloads/yt-x86_64/lib FTYPE_LOCATION: freetype found in: /usr/include, /usr/lib HDF5_LOCATION: HDF5_DIR: /home/mike/Downloads/yt-x86_64/include, /home/mike/Downloads/yt-x86_64/lib running develop running build_scripts running egg_info running build_src running build_forthon error: No such file or directory I've double checked all the dependencies and they are all installed and up to date. The stable version installs fine, if that matters. If you need my full install log, let me know. Thanks, Mike
